The micromineralogy and microstructure of the 'carbonaceous chondrite' clast from Bencubbin were investigated using analytical TEM and other electron beam techniques. It was found that, in section, the clast consists of oval augen set in fine-grained matrix; many subgrains have high densities of dislocations with 001-line-oriented Burgers vectors. The matrix of the clast contains abundant sulfides and fine-grained poorly crystalline Fe- and Fe/Ni-oxides, with more sparse ferrihydrite. There is evidence that one, or more, intense shock-heating events produced local melting, followed by shock events involving less severe shock-heating to about 900 C. The mineralogy of the clast indicates that it may have originated from a CM2 precursor or from material like Allan Hills 85085.
